Introduction

The AC12 allows you to connect up a system consisting of both the latest Meridian SpeakerLink products, and earlier Meridian products using Meridian Comms over either 5-pin DIN connectors or BNC connectors. The AC12 is a passive component and so is completely self-contained; it does not need a power supply or mains connection.
